[Esophageal diseases in patients with stenocardia and angiographically changes and little-changed coronary arteries].

Angiography conducted in 29 anginal patients has shown that coronary arteries were intact in 23 and little affected in 6 of them. Signs of myocardial ischemia were recorded at myocardial scintigraphy, bicycle ergometry, 24-h ECG monitoring in 17 patients. Esophageal lesions confirmed by endoscopy, manometry, esophageal pH-metry with Bernstein test were revealed in 20 examinees (68%). It is suggested that patients with persistent chest pain and unaffected coronary arteries who are resistant to antianginal therapy should undergo functional study of the esophagus including endoscopy, manometry and pH-metry.
